Some factors determine the existence of THC substance in your body, such as:

Body Mass (BMI)


Levels of THC Present in the Body

The normal timeline for THC to disappear in the body is different for each individual. This is because it relies on many factors that consider metabolism, body mass, age, duration of exposure, frequency of use, and the potency of the marijuana or cannabis consumed.

For many people, traces of THC from cannabis can take four to six weeks to naturally eliminate from the body from the last time they consumed it. Compared to other testable substances like heroin, THC is fat-soluble, meaning it gets stuck in the body organs and fat cells.

In general, if you consume less, you also need less time to cleanse or eliminate the substance in your body.

If you consume marijuana regularly or consume more, your body fat level will increase, making it longer to eliminate THC from your body. You will need detoxification and a diet plan if this is the case.

How do Drug Tests for Marijuana Work?

Cannabis leaves THC traces in the body’s fat cells, which deposit into the bloodstream and make these traces visible by drug tests, be it urine, hair, blood, or saliva.

Urine Analysis/ Urine Drug Test

Ng/mL or Nanograms per milliliter is the unit of measurement utilized in urine drug testing. Urine analysis can detect 50ng/ml or more of THC traces in the body.

Having 50ng of THC for every milliliter of urine means you are positive for drug use. However, this type of testing is the simplest to overcome through a detox drink or kit. This is effective in flushing out THC traces from your body.

There are two kinds of tests available for urine analysis. First is the immunoassay, which is considered the cheapest and the most common as it provides the fastest results.

However, it comes with some flaws. There are cases where this test provides a false result.

Another type of urine analysis test is the Gas Chromatography mass spectrometry test. This test is conducted to confirm the previous result, especially if it is positive.

However, this kind of testing is considered expensive as well as takes time to get the results. But, is considered reliable and trustworthy compared to another type of urinary analysis as it rarely provides false results.

Hair Tests

Hair drug tests are administered to determine whether or not you previously consumed drugs. This can show substance use from a quarter of a year to five days prior to taking the test.

The idea behind a hair drug test is that substance metabolites go into the blood vessel of your scalp, where they’re filtered and stored as a lasting record of a person’s drug use.

A lot of people oppose this kind of testing as it doesn’t test actual drug use. Since drug metabolites will stay in the hair scalp for a couple of months after use, they will stay there for long even if you take a bath regularly.

If you used cannabis a couple of months ago and undergo a hair test, the chance of having a positive result is higher.

Usually, this kind of test is time-consuming compared to urine analysis and blood tests. This drug test can detect various substances, including cannabis, opioids, PCP, methamphetamines, and cocaine.

While this test is used less often compared to urine tests at this point, sometimes this is used when an agency or company wants to figure out if somebody is a serious cannabis user.

Sad to say, a hair from your body and not from your head is able to register THC up to 12 months after the last time you consumed cannabis.

This makes this test difficult to overcome and generates a negative result. Some retailers do market-specific shampoo products, which are intended to wash the outer shaft of your hair strand which is where the substance is stored.

With a detox shampoo, it’s highly recommended that you conduct full body detoxification to get rid of THC from your bloodstream following your hair test schedule.

Blood Tests

Blood testing isn’t extensively utilized to test the presence of THC, largely due to the fact that this substance is normally just obvious via a blood sample up to 24 hours after the last time you take cannabis.

A hair sample is hard to beat as THC stays traceable in hair for longer than it appears in the urine. Urinalysis is the most common process and is also the simplest to pass if it has just been a day or two since you last used it.

Mouth Swab Tests

Mouth swab test is becoming more popular today. Thanks to technological advancement, it can now generate fast results with minimally invasive effort. Thus, they have been widely utilized to test anyone from drug users to applicants.

As marijuana has become commonplace, this test has grown in fame. This can be done on-site without a medical expert and the results can be acquired right away. The saliva sample is often hard to manipulate or tamper with.

Swab tests search for an array of compounds in the body while urine testing detects the THC-COOH metabolite. On the other hand, saliva drug tests look for THC.

It is easy to pass a saliva drug test for marijuana, at least for the time being, except you’re provided a test upfront. Knowing the purpose of the saliva test and how long you are at risk is vital to passing the test.

If you have a scheduled saliva test in the next couple of days, be ready; stop using cannabis at least for a day. If you don’t want to take a risk, you should refrain from using it. If you are told you need to undergo this test at the last minute, you can use detox mouthwash as your last resort to get a negative result.

Toxin detox mouthwash is very popular today. Just drink some, gargle it for a few minutes and then throw it out. Repeat if needed. Using hydrogen peroxide is also a popular way to clean your mouth from THC. This is also proven effective and at the same time doesn’t cost a lot.

In terms of cannabis, detoxing is a course that takes some time. Detoxing for a couple of days or even a couple of weeks is advisable. But not all have enough time to do the detoxification.

To speed up the process of detoxification, there are many choices available, but some of these are proven effective while the others are just hyped. To assist you to make a sound choice when choosing the best method, here are some of the best options available.
